Green Tech Hvac Services - Raleigh's Emergency HVAC Repair

That sounds like short cycling, a common issue in our area often caused by an oversized unit, a dirty air filter, or low refrigerant from a leak. Short cycling strains the system and hikes up energy bills. Our Green Tech technicians will diagnose the root cause—checking for leaks, cleaning components, and assessing sizing—to make the right repair so your system runs efficiently and lasts longer.

Raleigh's temperature swings can stress your system's coils and connections, leading to leaks. Our preventative maintenance includes checking refrigerant levels, inspecting coils and lines for early signs of wear, and tightening electrical connections. Catching a small issue early during a tune-up can prevent a major leak, saving you from costly repairs and keeping your system cooling effectively all season.

Proper sizing is critical. An oversized unit, a past mistake in our climate, cools too quickly and shuts off, causing short cycles. Our Green Tech team performs a detailed Manual J load calculation for your specific Raleigh home, considering insulation, windows, and layout. We recommend a correctly sized, high-efficiency system that runs in longer, more efficient cycles, providing even comfort and lower energy bills for years to come.
